Objectives: Information of chemical in electronics industry has not been known enough, although workers' health hazards by chemicals in this industry have been regarded serious. The who always contribute to reveal and control the health hazards and risks in electronics industry were not the industry but the occupational or environmental victims and grassroot organizations. The similar phenomena can be observed in Korea. Methods: The experiences of individual workers on the occuapational safety and health in semiconductor factory were heard separately and integrated with related literatures. Results: The first part of this article is largely based on the memories and experiences of individual workers of semiconductor factories, mainly from S semiconductor. Common features of those experiences can be a good resource for detail understanding of the workplace, especially under the situation without any transparent disclosure of information by the governments or the companies. The second part of this article deals with several factors to be considered for control of exposure in workplace; characteristics of workplace and workforce, types of chemicals used, and the way of using the chemicals. Then the current social issues on work-relatedness of cancers of S semiconductor workers are presented briefly. Conclusions: As a conclusion, current OSH situations and issues in Korean electronics industry raise the need of changes in OSH culture. General adaptation of precautionary principle, internalization of costs, and extended responsibility of producers is needed urgently. The OSH professionals both in public and private sectors should support these agendas under their social obligation to protect workers' health.

고상백,손미아,공정옥,이철갑,장세진,차봉석 大韓産業醫學會 2004 대한직업환경의학회지 Vol.16 No.1

목적: 이 연구는 정규직 근로자들과 비교하여 비정규직 근로자들의 직무스트레스 요인으로서 직무요구도, 직무자율성, 그리고 직무불안정의 차이를 분석하고, 직무스트레스 결과로 발생하는 사회심리적 스트레스에 영향을 주는 요인을 파악하고자 한다. 방법: 이 연구는 영남지역에 위치한 조선업종을 대상으로 원청 사업장 2개 회사의 정규직 681명과 하청업체 40개 회사의 하청근로자, 일용직, 계약직 근로자 1,032명으로, 총 연구대상자는 1,713명이었다. 자료수집 방법은 사업장을 방문하여 연구의 취지를 알린 후 구조화된 설문지를 이용하여 조사자 직접 기입법으로 사회인구학적 특성, 직업적 특성, 사회심리적 스트레스 수준 등에 대하여 설문 조사를 하였다. 사회심리적 건강수준에 미치는 요인을 파악하기 위하여 사회인구학적 특성(성, 연령, 학력, 결혼상태), 직무특성(근무년수, 급여, 주 평균근무시간, 고용형태, 실직, 이직 등), 직무요구도, 직무자율성, 사회적지지, 직업불안정을 독립변수로 하여 다중회귀 분석을 시행하였다. 결과: 정규직과 비정규직의 직업적 특성의 차이를 알아보기 위해 단일변량 분석한 결과, 유의한 차이를 보인 변수는 흡연, 취미생활, 불충분한 수면, 근무기간, 주당 평균 노동시간, 이직, 실직, 직무요구도, 직무자율성, 사회적지지 및 직업불안성 등이었다. 직업성긴장 수준에 따른 분포는 고긴장집단의 경우 정규직의 비해 비정규직이 훨씬 많은 분포를 보였고, 고립된 고긴장집단(iso-strain group) 역시 정규직에 비해 비정규직이 유의하게 많은 분포를 보였다. 사회 심리적 스트레스에 영향을 미치는 요인을 파악하기 위하여 다중회귀 분석을 시행하였다. 일반적 특성에서는 연령이 유의한 변수였으며 나이가 젊을수록 스트레스가 높았다. 직무특성에서는 과거 실직경험이 있거나 이직 경험이 있는 경우 스트레스가 높았으며, 고용형태는 정규직보다 비정규직에서 스트레스가 높았음을 보여주었다. 직업적 특성에서는 직무요구가 높을수록, 사회적지지가 낮을수록, 직업불안정이 높을수록 스트레스가 높았으며 유의한 결과를 보여주었다. 결론: 이 연구를 통해 비정규직 근로자의 사회심리적 건강수준이 정규직 근로자와는 다른 실직경험, 이직경험 및 직업불안정 등 다양한 직무스트레스 요인에 의해 부정적인 영향을 주고 있다고 추정 할 수 있다. 향후 객관적인 건강지표의 비교분석을 통한 비정규직의 건강문제에 대한 더 많은 연구가 필요하다고 생각된다. Objective: This study was conducted to compare the job characteristics (work demand, decision latitude, and job insecurity) and psychosocial stress levels of typical workers in the parent firm, to those of atypical workers in subcontracted firms. In addition the risk factors for psychosocial stress of atypical workers are evaluated. Method: The study design was cross-sectional, and 1,713 shipbuilding workers (681; typical workers, 1,032; atypical workers) were recruited. A structured-questionnaire was used to assess the general characteristics, job characteristics and psychosocial stress levels. We used the chi-square test for univariate and multiple regression analyses. Results: In univariate analyses, there were significant differences in smoking, hobby, insufficient sleeping, work hours per week, quitting, unemployment, job decision latitude and job insecurity. The job strain was significantly higher in the atypical workers than in the typical workers. The proportion of iso-strain groups was significantly greater in the atypical workers than typical workers. Using psychosocial stress as the dependent variable, multiple regression models were estimated. After adjustment for sociodemographic factors, unemployment, quitting employment type, job demand, job decision latitude and job insecurity were all found to be significantly associated with psychosocial stress. Conclusion: This result suggests that the psychosocial stress of atypical workers is related to job characteristics such as job insecurity and labor flexibility.

Objectives : The objective of this study is to compare the circadian patterns of heart rate variability assessed by 24-hour ambulatory electrocardiographic (ECG) recordings during day shift and night shift among the workers in the 5 days-concecutive-12-hour shift in an automobile factory in Korea. Methods : The study population consisted 300 workers, who were randomly selected among the 8700 total workers in one car factory. To analyse circadian variation, the 24-hour ECG recordings (Marquette) were measured during day shift (08:00-20:00 h) and night shift (20:00-08:00 h). Analysis was performed for all time and frequency domain measures of HRV. 233 workers completed taking 24-hour ECG recordings. Results : This study shows that the 24 hourcircadian variation mainly follows work/sleep cycle rather than day/night cycle among shift workers. This study also shows that among the night shift, the circadian variation between work and sleep cycle decreased compared to the work/sleep cycle among day shift workers. All time and frequency domain parameters (except LF/HF ratio) show significantly different between work and sleep in the day shift and night shift. Conclusion : These changes in heart rate variability circadian rhythms reflect significant reductions in cardiac parasympathetic activity with the most marked reduction in normal vagal activity among the shift workers. Especially, it suggests the circadian rhytm has blunted among the night workers. The quantification of the circadian variation in HRV can be a surrogates of workers' potential health risk, as well as suggests possible mechanisms through which the shift works compromise workers' health.

우리나라의 1995-2004년도 출생코호트에서 부모의 사회계급이 영아사망률과 소아사망률에 미치는 영향

Objectives : To investigate the effect of parents' social class on infant and child mortality rates among the birth cohort, for the period of transition to and from the Koran economic crisis 1995-2004. Methods : All births reported to between 1995 and 2004 (n=5,711,337) were analyzed using a Cox regression model, to study the role of the social determinants of parents in infant and child mortality. The results were adjusted for the parents' age, education and occupation, together with mother's obstetrical history. Results. The crude death rate among those under 10 was 3.71 per 1000 births (21,217 deaths among 5,711,337 births) between 1995 and 2004. The birth cohorts from lower educated parents less than elementary school showed higher mortality rates compared with those from higher educated parents over university level (HR:3.0 (95%CI:2.8-3.7) for father and HR:3.4 (95%CI:3.3-4.5) for mother). The mother's education level showed a stronger relationship with mortality among the birth cohort than that of the fathers. The gaps in infant mortality rates by parents' social class, and educational level became wider from 1995 to 2004. In particular, the breadth of the existing gap between higher and lower parents' social class groups has dramatically widened since the economic crisis of 1998. Discussions : This study shows that social differences exist in infant and child mortality rates. Also, the gap for the infant mortality due to social class has become wider since the economic crisis of 1998.

Visual acuity impairment among children can lead to learning and behavioral disabilities. This study was carried out to describe the prevalence and risk factors of visual acuity impairment in Korean preschool children. Subject of this study was aged 4-6 children (n=2179) attending nursery and day-care centers of one district of Seoul City. The children were examined with Standard Visual Chart with diagrams familiar to children. If the visual acuity was equal to or less than 0.6, then it was described as impaired visual acuity. Age and sex were examined as for their associations with impaired visual acuity together with indicators of physical developments such as height, weight, and hemoglobin concentration. Based on the multiple logistic regression using SAS v 8.02, age and low birth weight were significant risk factors for impaired visual acuity, while other factors including parent's smoking history, housing environment, breast feeding history or diet habit were not. The results of this study indicate the importance of fetal environment/experiences in preventing impaired visual acuity. Possible role of incubators for low birth weight babies should also be considered.
